Which statement about hexadecimal values is true?

a. refers to the base 10, rather than base 16 numbering system

b. colors are defined in two-digit red, green, and blue (rgb) values

c. use defined names for colors

d. all of the above

B. Colors are defined in two-digit red, green, and blue (RGB) values.

Explanation:

RGB stands for Red Green and Blue. All colours can be made by mixing these three colours. We use hexadecimals to do this. How it works is we assign bits to colours. Let's say we have 256 bits for Red ranging from 0-255. in hexadecimal the range is 00 - FF. 00 is 0 and FF is 255. All colours of the RGB can be represented by the RGB hexadecimal values that are comprised of 2 digits.

A is incorrect because hexadecimal has a bad of 16.

C is incorrect because we do not use defined names for colours as explained above.
